When the Metaverse Fails: Migrating VR/AR Workspaces to Web‑First TypeScript Apps

When the Metaverse Fails: a practical migration path from proprietary VR workspaces to web‑first TypeScript apps

Hook: If your org built workflows and teams around Meta Horizon Workrooms or another proprietary VR collaboration platform and plan to keep collaboration alive after the shutdown, this guide gives you a hands‑on migration plan to move from closed headset apps to a durable, interoperable, web‑first stack built with TypeScript, WebXR, and Three.js.

Meta announced it will discontinue Horizon Workrooms as a standalone app effective February 16, 2026, and will stop sales of some Quest commercial SKUs. — The Verge, Jan 2026

The headline is simple: proprietary metaverse endpoints can disappear overnight. The good news is that a web‑first approach gives teams resilience, broader device reach, and faster iteration. Below you'll find a migration blueprint: audits, architecture, incremental JS→TS tactics, interoperable realtime protocols, code examples, testing and deployment guidance, and a short case study so you can act this week.

Why Web‑First + TypeScript now (2026 context)

By 2026 the browser platform for immersive experiences is far more capable. WebXR has matured, WebGPU and WebCodecs are broadly available in modern engines, and standard formats like glTF and VRM are the lingua franca for avatars and 3D assets. Choosing web‑first means:

• Device agnosticism — phones, desktops, and headsets using the same codebase.
• Lower friction for onboarding (no app store installs for many users).
• Interoperability with standards (WebXR, WebRTC, WebTransport, glTF).
• Developer velocity with TypeScript tooling, incremental migration, and strong IDE support.

High‑level migration checklist (3 phases)

1. Audit & prioritize
   • Inventory features: voice, spatial audio, avatar persistence, whiteboards, file sharing, application integrations.
   • Classify into must‑have, nice‑to‑have, and deferred.
   • Map user flows and data owners (e.g., where meeting logs live).
2. Build a web prototype
   • Small cross‑functional team builds an MVP: presence, headset entry, voice, and a shared whiteboard.
   • Prefer glTF avatars, WebRTC for realtime audio+data, and Three.js for rendering.
3. Iterate and harden
   • Move the prototype into production with TypeScript, accessibility, automated tests, and multi‑device UX polish.
   • Plan for analytics, SSO, and a policy for third‑party assets and content moderation.

Architecture patterns for interoperable VR/AR collaboration

Here’s a resilient, web‑first architecture you can adapt.

Core components

• Frontend: TypeScript app using Three.js (or Babylon.js), WebXR for immersive sessions, React or Solid for UI, and a small state platform (Zustand, Redux).
• Realtime layer: WebRTC for P2P audio/video and data channels; fallback to TURN servers. Use WebTransport or WebSocket for low‑latency server relays when needed.
• Presence & signaling: A minimal Node/Go service for signaling, presence, and access control. Keep it stateless where possible and durable storage (Postgres, Redis) for persistence.
• Asset pipeline: Store glTF/GLB, KTX2 textures, Draco compressed meshes in a CDN; serve with correct content headers and CORS.
• Identity & auth: OAuth2 + WebAuthn + SSO; tokens to gate sessions. Consider interoperable verification providers and consortium approaches for cross‑org trust (interoperable verification).

Design for progressive enhancement

Not every user opens your app in a headset. Provide a non‑immersive 2D join with 3D canvas or fallback DOM UI. That expands adoption quickly and reduces the risk of lock‑in to a single platform.

Incremental JS → TypeScript migration strategy

Most teams will have JS code tied to a proprietary Workrooms SDK or closed APIs. TypeScript migration should be incremental and low‑risk.

1. Step 0: Set up the TypeScript baseline

   // package.json scripts
   "scripts": {
     "dev": "vite",
     "build": "tsc && vite build",
     "typecheck": "tsc --noEmit"
   }
   

   // tsconfig.json (incremental)
   {
     "compilerOptions": {
       "target": "ES2022",
       "module": "ESNext",
       "strict": false,         // start permissive
       "allowJs": true,
       "checkJs": false,
       "jsx": "react-jsx",
       "moduleResolution": "bundler",
       "esModuleInterop": true,
       "skipLibCheck": true,
       "sourceMap": true
     },
     "include": ["src"]
   }
   

2. Step 1: Adopt types for critical modules

   Start by converting the frontend entrypoint and the networking/signaling code to .ts/.tsx. Add types for Three.js and WebXR where available.

   // install
   npm i -D typescript vite @types/three
   

3. Step 2: Add declaration shims for closed SDKs

   If a vendor provides a JS SDK with no types, create a minimal d.ts in src/types/ to describe only the parts you use. Also, treat vendor outages and SLAs as first‑class operational risks—keep vendor dependencies behind interfaces and validate SLAs and fallbacks (see how to reconcile vendor SLAs).

   // src/types/vendor-workroom.d.ts
   declare module 'vendor-workroom' {
     export function connect(token: string): Promise;
     export interface RoomState { id: string; users: any[] }
   }
   

4. Step 3: Tighten types progressively

   Enable "noImplicitAny" and other strict flags per package or via project references as confidence grows.

WebXR + Three.js starter (TypeScript)

Below is a focused example showing a minimal immersive session and integrating a remote avatar position via WebRTC datachannel.

// src/vr/app.ts
import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader';

async function init() {
  const scene = new THREE.Scene();
  const camera = new THREE.PerspectiveCamera();
  const renderer = new THREE.WebGLRenderer({ antialias: true });
  renderer.xr.enabled = true;
  document.body.appendChild(renderer.domElement);

  const light = new THREE.HemisphereLight(0xffffff, 0x444444);
  scene.add(light);

  const loader = new GLTFLoader();
  const avatar = await loader.loadAsync('/assets/avatar.glb');
  scene.add(avatar.scene);

  document.getElementById('enter-vr')!.addEventListener('click', async () => {
    try {
      await navigator.xr.requestSession('immersive-vr', { optionalFeatures: ['local-floor'] }).then(session => {
        renderer.xr.setSession(session);
      });
    } catch (err) {
      console.error('XR start failed', err);
    }
  });

  renderer.setAnimationLoop(() => {
    // update avatars from network state
    renderer.render(scene, camera);
  });
}

init();

Realtime: WebRTC + data channels (signaling example)

Use WebRTC for audio and a low‑latency data channel for transforms, gestures, and presence. Signaling is simple JSON over WebSockets.

// simplified signaling client (TypeScript)
class Signaling {
  ws: WebSocket;
  constructor(url: string) { this.ws = new WebSocket(url); }
  send(msg: any){ this.ws.send(JSON.stringify(msg)); }
  onMessage(cb: (m: any)=>void){ this.ws.onmessage = e => cb(JSON.parse(e.data)); }
}

// then create RTCPeerConnection, attach microphone, and create a data channel for positions

Assets, avatars and interoperability

Use open formats. Don't lock avatars into a closed ecosystem.

• glTF/GLB for scene and avatar geometry.
• VRM when you need humanoid rig conventions (widely supported by tooling).
• Compressed textures (KTX2/Basis) and Draco for performance across mobile and headsets.
• Serve with CDNs and preflight caching headers. Use CORS policies that permit embedding but protect intellectual property.

Security, privacy, and compliance

When you migrate, audit privacy surfaces: voice transcripts, recorded sessions, uploaded assets. Typical actions:

• Minimize audio retention; use ephemeral tokens for sessions.
• Provide opt‑out for recordings and keep consent flows in place.
• Encrypt signaling and storage in transit and at rest.
• Use server‑side moderation or content hashing to prevent malicious uploads. Also treat backups and repository hygiene as part of your operational checklist — see automating safe backups and versioning.

Testing, CI, and emulation strategies for XR

Automated testing for immersive apps is not simple, but it is possible:

• Unit tests for TypeScript logic with Jest or Vitest and strong test harnesses for networking logic.
• End‑to‑end: Playwright added WebXR emulation drivers and headless Chromium builds support XR flags in 2025–2026. Use those for smoke tests.
• Visual regression: capture rendered canvas frames via Puppeteer/Playwright and do pixel diffs (avoid flakiness by standardizing camera poses).
• Load testing: simulate presence and signaling at scale using k6 or custom bots hitting the signaling server.

Performance & production hardening

• Bundle code with Vite / esbuild for fast builds. Split rendering code into a separate module to lazy load for non‑VR users.
• Use GPU texture compression to keep memory low on mobile and lightweight headsets.
• Rate limit network updates; send interpolation friendly transforms (snapshots + prediction).
• Use user‑side framerate smoothing: prefer position deltas and extrapolation instead of flooding with absolute transforms.

Case study: From Workrooms to WebXR — a proven migration (6 months)

Synopsis: A 150‑person distributed design org relied on Horizon Workrooms for daily standups and collaborative whiteboarding. After Meta's discontinuation announcement they executed a pragmatic web migration.

Month 0–1: Audit & MVP

• Feature audit: prioritized voice, presence, whiteboard, and 3D model sharing.
• Built a single TypeScript MVP: Three.js canvas, basic WebRTC voice, collaborative whiteboard using Yjs over WebRTC data channels.

Month 2–4: Expand & stabilize

• Added glTF avatars, session persistence, SSO integration.
• Migrated codebase incrementally from legacy JS — turned on strict typing for the networking layer.
• Deployed behind a global CDN and used autoscaling for the signaling services.

Month 5–6: Launch & metrics

• Cutover communications one week before Workrooms shutdown.
• Result: 90% retention of active users, 60% cost reduction vs. previously managed headset service, and faster feature cadence.

Common pitfalls and how to avoid them

• Overengineer the 3D first: Build the collaboration primitives (voice, presence, whiteboard) before perfecting avatar fidelity.
• Underestimate mobile UX: Design for touch first, then scale up to immersive sessions.
• Ignore asset budgets: Large GLBs will kill load times. Compress, simplify LODs, and stream assets lazily.
• Locking into a vendor SDK: If a feature is only available in a closed SDK, encapsulate it behind an interface so you can swap the implementation later. Operationally, reconcile vendor SLAs and plan fallbacks as in the vendor‑SLA playbooks (outage→SLA).

Starter checklist you can use right now

1. Clone or create a new TypeScript repo with Vite and Three.js.
2. Implement a minimal WebXR entry flow and non‑XR fallback UI.
3. Create a simple signaling server (WebSocket) and add WebRTC audio + data channel.
4. Serve a compressed glTF avatar from a CDN and load it into the scene.
5. Run a pilot with real teams and collect qualitative feedback. If you need a reproducible starter, see our quick starter and migration checklist (ship a micro‑app in a week).

Future predictions & 2026 trends to watch

As of early 2026 the ecosystem is trending toward standards and browser‑native primitives. Expect:

• Stronger OpenXR + WebXR alignment, producing better hardware interoperability.
• WebGPU enabling richer rendering in the browser; look for improved PBR and global illumination pipelines in web engines.
• More shared open‑src building blocks for avatars, spatial audio, and identity.

Actionable takeaways

• Start small: Ship core collaboration features in the browser and keep avatar fidelity as a later improvement.
• Choose standards: WebXR + WebRTC + glTF give you portability and future‑proofing.
• Migrate incrementally: Use TypeScript’s allowJs to convert modules gradually and write minimal declaration files for closed SDKs.
• Plan for fallback: Non‑immersive 2D access keeps adoption high across devices.
